Those guns are quite dissimilar. I have the 11-87 and SA -08. The Weatherby Waterfowler 3.0 is my favorite if I need to walk very far. It is much lighter and quicker handing than my other duck guns. Really a good all around field gun.
None are particularly good trap guns, so pick your poison. They are lower priced field guns and tend to shoot flat.
Well, are you gonna pull those pistols or whistle Dixie?
